[Linux-cluster] What is the proper way to grow LVM/GFS volumes

[Alan A]

I tried a few times to grow LVM by adding additional PV to VG, and then
executing 'lvextend' command. I am not sure what I am doing wrong but I get
the message that there is error locking on one of the nodes, and then the
GFS hangs.

Here are some of the details:

[root at fenmrdev03 ~]# vgs
  VG         #PV #LV #SN Attr   VSize  VFree
  VolGroup00   2   2   0 wz--n- 50.75G    0
  gfs_sda1     1   1   0 wz--nc 10.00G 5.00G
  gfs_sdb1     1   1   0 wz--nc 10.00G 3.00G
  nuvg4        2   1   0 wz--nc 10.00G 5.00G
[root at fenmrdev03 ~]# lvs
  LV       VG         Attr   LSize  Origin Snap%  Move Log Copy%  Convert
  LogVol00 VolGroup00 -wi-ao 40.81G
  LogVol01 VolGroup00 -wi-ao  9.94G
  gfs_sda1 gfs_sda1   -wi-ao  5.00G
  gfs_sdb1 gfs_sdb1   -wi-ao  7.00G
  nulv4    nuvg4      -wi-ao  5.00G
[root at fenmrdev03 ~]# pvs
  PV                VG         Fmt  Attr PSize  PFree
  /dev/cciss/c0d0p2 VolGroup00 lvm2 a-   33.81G    0
  /dev/cciss/c0d1p1 VolGroup00 lvm2 a-   16.94G    0
  /dev/sda1         gfs_sda1   lvm2 a-   10.00G 5.00G
  /dev/sdb1         gfs_sdb1   lvm2 a-   10.00G 3.00G
  /dev/sdc          nuvg4      lvm2 a-    5.00G    0
  /dev/sdd          nuvg4      lvm2 a-    5.00G 5.00G


Command I tried:
[root at fenmrdev03 ~]# lvextend  -l100%FREE  /dev/nuvg4/nulv4
